They haven’t stopped the emerald ash borer plague in any other state either, this article is pure BS. The fact that it asserts that all is well because there are lots of little sapling ash trees is either meant to be misleading or just plain ignorance, i.e. emerald ash borers don’t go after saplings, and the saplings we have are those produced by the mature trees just before the beetles killed them.
Where did the narrator ever assert that all is well?
